Analog Devices Inc./Maxim Integrated MAX364CSE

Overview

The MAX364CSE from Maxim Integrated is a precision quad SPST analog switch with normally closed (NC) configuration, designed for high-fidelity signal routing in precision instrumentation and test equipment. It delivers <85Ω on-resistance, <2Ω channel-to-channel matching, <10pC charge injection, rail-to-rail analog signal handling (±15V), and operates from ±4.5V to ±20V dual supplies or +10V to +30V single supply.

For engineers reviewing the MAX364CSE datasheet, MAX364CSE pinout, MAX364CSE application, or MAX364CSE equivalent, key selection criteria include guaranteed on-resistance flatness (∆9Ω max), low leakage (<4nA at +85°C), fast switching (t_ON < 250ns), and ESD robustness (>2000V), especially in battery-operated or military-grade analog front-ends.

Technical Context

The MAX364CSE implements four independent CMOS-controlled SPST switches with NC topology, fabricated using Maxim's 44V silicon-gate process. Its architecture ensures matched on-resistance across all channels and minimal variation over full analog signal range (–15V to +15V), critical for multiplexed sample-and-hold and precision gain-switching circuits.

It supports TTL/CMOS logic inputs (VL = 5V or V+) and maintains rail-to-rail analog conduction without signal clipping. Dual-supply operation enables true bipolar signal switching, while single-supply mode (+10V to +30V) simplifies power design in portable systems-both modes retain low 35µW quiescent power and sub-250ns switching performance.

Key Specifications

Pinout & Package

The MAX364CSE is housed in a 16-pin narrow SOIC (SO) package with 0.150" body width, JEDEC MS-012 compliant, lead pitch 1.27mm, and exposed pad connected to V+ for thermal enhancement.

FAQ

What is the maximum analog signal voltage range supported by the MAX364CSE?

The MAX364CSE supports a full analog signal range from V− to V+, enabling rail-to-rail operation. With ±15V dual supplies, it handles signals from –15V to +15V. When operated from a +30V single supply (V− = GND), the range is 0V to +30V. Absolute maximum ratings allow up to ±20V supplies and ±15.5V signal swing relative to supplies, with breakdown voltage rated at 44V.

Is the MAX364CSE pin-compatible with the MAX364ESE?

Yes, the MAX364CSE and MAX364ESE share identical pinout, package (16-pin narrow SO), and electrical specifications-differing only in temperature rating (0°C to +70°C vs. –40°C to +85°C). No PCB layout changes are required when upgrading to the extended-temperature variant for harsher environments.

Does the MAX364CSE require a separate logic supply voltage (VL)?

Yes, the MAX364CSE uses VL (Pin 7) to set logic threshold levels. For TTL compatibility, connect VL to +5V; for CMOS compatibility, tie VL to V+. Leaving VL unconnected or floating is not permitted-doing so may cause undefined switching behavior or increased power consumption in the MAX364CSE.

How does the normally closed (NC) configuration of the MAX364CSE affect system behavior during power loss?

The MAX364CSE's NC topology ensures that all four switches remain conductive (COM connected to NC) when IN inputs are low or unpowered. During power loss, the switches default to closed state-providing fail-safe signal continuity in safety-critical paths such as sensor monitoring or emergency shutdown circuits, unlike NO devices which open under fault conditions.

Can the MAX364CSE be used with unbalanced supplies, such as +24V and –5V?

Yes, the MAX364CSE supports unbalanced supplies. The key constraint is that the difference between V+ and V− must not exceed +44V, and each supply must stay within its absolute maximum rating (V+ ≤ +44V, V− ≥ –44V, GND ≤ +25V). For example, +24V and –5V yields a 29V differential-well within spec-and enables asymmetric signal range optimization in custom power architectures.
